A total number of 201 surface soil samples were collected encompassing the fields of Central Farm of Horticultural College and Research Institute, Periyakulam, Tamil Nadu. The GPS data (Latitude ºN and Longitude ºE) were recorded for each sampling site by using GPS-Garmin eTrex Vista HCX model. Field maps were collected and field number wise digitization was done. Soil samples were processed and anlaysed for soil physic-chemical and fertility parameters. Results indicated that soil samples were neutral to alkaline in reaction, non saline, and slightly calcareous to non calcareous in nature. Soil fertility groupings under percent category indicated that the soils were medium in soil organic carbon, low in available nitrogen, medium to high in available phosphorus, medium to high in available potassium, and low in available sulphur. With respect to DTPA extractable micronutrients, Fe, Zn, Mn and Cu were found to dominate by low to medium, low, high, medium to high categories, respectively. HWS-Boron was also recorded under the high category. The nutrient index values of the samples indicated a high status for organic carbon, available P and K, while medium for available N and adequate for available sulphur. With respect to micro nutrients, nutrient index values indicated that adequate for DTPA-Zn and very high for DTPA-Fe, Mn, Cu, and HWS-B. Thematic maps generated on the individual parameters depicted the spatial variability of parameters in the Central Farm of Horticultural College and Research Institute, Periyakulam. In the identified areas of poor fertility status, nutrient deficiency has to be eliminated by the application of organic and /or inorganic sources to maintain sustainable soil fertility status. Soil test-based fertilizer recommendations and micronutrients are to be followed to mitigate nutrient deficiencies and achieve sustained crop production and soil fertility.

Soil Fertility Status

An investigation was under taken to study the soil fertility status of major nutrients, micronutrients and mapping in Ramasamudram-1 microwatershed of Yadgir taluk and district of Karnataka, India during the year 2019. Total seventy-four grid wise surface soil samples were collected at 320 m grid interval at 0-15 cm depth to assess the soil parameters (texture, pH, EC, OC, available P, K, S, Zn, Cu, Fe, Mn and B) and prepare the soil fertility maps through GIS using Kriging method. The results of the study indicated that, the texture of the soil varied from loamy sand to sand clay loam in surface. Soil reaction varied from acidic to neutral with non-saline in nature. The distribution of soil organic carbon (32%), available phosphorous (56%) and potassium (47%) status was found to be medium in most of the area of microwatershed. The available sulphur status was found to be low (57%) in maximum area of the microwatershed. The available zinc status was found to be sufficient (46%) in majority area of the microwatershed. The available copper, iron and manganese status of the soils were sufficient (58%) in entire area. Whereas available boron status was found to be low (57%) in maximum area of the microwatershed. Therefore, the study showed that, the soils of the microwatershed were medium in fertility status. There is need of proper fertilizer recommendation and soil management practices can be made productive thereby, increasing the crop yield.
